First, the original data C is divided into an n number of pieces of partial data C1-Cn. Then pieces of position information P1-Pn are added to those pieces of divided partial data, and they are respectively embedded into the n number of duplicated images. Then, the resultant images E1-En are produced. The resultant images are displayed in the same position on a display screen as a still image for T1 seconds each. In a camera of a mobile phone, etc., the displayed images are repeatedly photographed at an interval of T2 seconds that is shorter than T1 seconds, and the pieces partial data C1-Cn and position information P1-Pn are sequentially extracted. When all the processes are completed, the pieces of partial data are integrated on the basis of the pieces of position information P1-Pn. As a result, the original data is obtained. |
